유연성 차이에 따른 프로 배구 선수들의 근력, 심폐지구력 및 점프력에 미치는 영향

The aim of this study was to investigate the effects of flexibility on the muscle power, cardiopulmonary enduracne, and junping ability of professional volleyball players. The subjects of the study were 43 professional volleyball players. Subjects were classified into three group a flexibility test in advance(GroupⅠ: minimal flexibility, GroupⅡ: moderate flexibility, GroupⅢ: maximal flexibility). Kin-Com was operated to find out the maximum muscle power of the subjects according to flexibility, and cardiopulmonary endurance was used by Havard Staff and jumping ability was used by servant jumping. In addition, Muscle power and cardiopulmonary endurance, jumping ability were analyzed using one-way ANOVA test, and Fisher’s least significant difference(LSD) was used for post-verification. As a results of the study, there was a significant difference in the maximum muscle power of 180° flexion and extension of the knee joint according to flexibility(p< .05). there was also a significant difference in servant jump. As a result of post-analysis as flexibility increased, there was a significant improvement in maximum muslce power and jumping ability. Based on these results, when planning programs to improve athlete’s personal muscle power and exercise performance, exercise programs to improve flexilibity as well as stretching performed in warm-up and cool-down exercises should be organized.
